Title: Current detecting circuit
Inventor: NUNOKAWA YASUHIRO
IPC: H02M3/155
Filed: 1988-04-13
Abstract: PURPOSE:To obtain a high-accuracy detection current which is proportional to a driving current flowing to an output transistor (TR) by coupling the source potential of an output MOSFET with the source of a MOSFET for current detection. CONSTITUTION:When an input signal IN is held at L, a MOSFET Q6 turns off. A triangular wave generating circuit RPG starts operating to generate a lamp voltage VR and also reset a circuit FF. Further, a MOSFET Q7 is also off, so a boosted voltage Vcc+Vth which is generated by a boosting circuit BST is supplied to the gate of an MOSFET Q1 through a resistance R4 to turn on the MOSFET Q1. Thus the FET Q1 turns on to supply a turning-on current Id to a lamp and the current Id has a large current value when the lamp begins to light. A sensor current Is also increases correspondingly to the current Id, so it is converted to a high voltage Vsl. This voltage VR reaches the voltage Vsl, so a voltage comparing circuit CMP detects that and sets a circuit FF.

On the other hand, an audio AGC amplifier 6 amplifies and outputs an audio signal. At such a time, a feedback circuit 7 generates an audio AGC voltage for controlling the gain of the audio AGC amplifier 6 and applies it to the adder 10. The audio AGC voltage and the video AGC voltage are added by the adder 10 and applies to the audio AGC amplifier 6. Thus, the gain of the audio AGC amplifier 6 can be controlled based on the change of the video AGC voltage and the audio output corresponding to the luminance level can be obtained.
